Several ultrasounds are requested during pregnancy and the baby is "photographed" during its development in utero, to the delight of parents.
Obstetric ultrasound is in fact done to study the fetus, its development, its cardiac activity, its movements, to look for possible malformations. It is necessary to think of drinking well before passing the examination, so that the bladder is full to allow a perfect transmission of ultrasonic rays.
In gynecology, ultrasounds are often prescribed to visualize the genitals, the ovaries for example in search of a cyst, to visualize the uterus in search of a fibroid, ...
One can use either an abdominopelvic probe that the doctor passes on the skin of the belly, a vaginal probe introduced into the vagina, to better visualize the ovaries and the tubes for example.

Throughout pregnancy, fetal development can be monitored by regular ultrasounds. Ultrasound is an examination that examines internal anatomy using high-frequency sound waves. Explanations in video ...
To examine arteries, veins and heart
Ultrasound has an important place, it is coupled to Doppler.
As much as ultrasound can visualize static anatomical structures, the Doppler studies dynamic images such as the speed or direction of blood flow, the light of the vessels and heart chambers are well visualized and we can distinguish dilations, narrowing, obstacles on the blood path.
The speed of the blood can be objectified by the continuous Doppler which will give a sound, by the pulsed Doppler which will translate it by a curve; the color Doppler coupled with the ultrasound will make it possible to obtain images with the colored vessels in red, blue or yellow.
For example, this examination is interesting to study the veins of the lower limbs and to take stock of venous insufficiency or thrombophlebitis before eventually performing a therapeutic surgical procedure: the ultrasound makes it possible to visualize the vein walls, the state of the valves, to objectify the presence of a blood clot, its situation, its size ... the Doppler ultrasound refines the examination and makes it possible to diagnose a insufficiency of the valvular function and a blood stasis.
Ultrasound is also indicated to study the arteries of the body: as for the veins, it is possible to visualize their walls and the interior of the artery: to highlight a thickening of the wall, the presence of a plaque of atheroma, or to analyze the size and shape of an aneurysm ... we study thus the arteries of the limbs, the aorta, the carotid artery, certain arteries of the brain, etc.
Cardiac echocardiography visualises the cavities and the heart muscle, it makes it possible to highlight a possible valvular insufficiency or a narrowing at their level, the Doppler echo will visualize for example an anomaly of the game of the heart valves, of the cardiac cavities which fill up badly, a hypertrophied heart muscle ...
